Vector Optics 34 mm Steel Mounting Rings Medium — Matte Black

Steel mounting rings with a 34 mm inner diameter, designed to mount riflescopes on 21 mm Picatinny rails. A center-height of 35 mm places them in the Medium category, suited to most scopes with mid-size objectives on bolt-action and semi-automatic rifles. These are aimed at the demanding shooter who will not compromise on the rigidity of the optic-to-rifle connection.

The 6063-T6 alloy construction delivers a better strength-to-weight ratio than die-cast iron: the rings weigh 165 g combined, keeping added mass low without sacrificing structural rigidity. The manufacturer explicitly rates these for use on live-fire firearms, with a maximum recommended torque of 2.8 N·m — a figure that guides correct installation and prevents both under-torquing, which causes shifting under recoil, and over-torquing, which can deform the scope body.

Each ring is secured by six screws across a 26 mm clamping width, distributed to minimise point pressure on the tube and maintain alignment even after extended shooting sessions or with heavy-recoiling calibres. The matte black finish reduces glare in raking light and integrates visually with most modern platforms.

Key features
